A latch for a cabinet door or drawer for preventing access to the interior of the cabinet or drawer. The latch includes a hook spring biased to engage a catch and that allows the door or drawer to be only slightly opened enough to allow a caregiver to reach the latch and displace it out of the way so that the door or drawer can then be fully opened. When released the latch returns to the biased position. The latch may also disengage the spring so as to be fully disabled and allow the door or drawer to be opened freely.
